 '''Description:''' FFmpeg contains an AAC encoder and decoder, and both of them can be improved in various ways. This is enough work for more than one GSoC project, so one part of your submission would be to define on which task exactly you want to work.
 
-    - AAC BSAC decoder: This has already been started, but the existing decoder still fails on many samples
-    - AAC SSR decoder
-    - AAC 960/120 MDCT window

+      - Implement [http://wiki.hydrogenaudio.org/index.php?title=Joint_stereo#Intensity_Stereo intensity stereo]
+      - Implement AAC LTP (long term prediction)
+      - Implement [http://en.wikipedia.org/wiki/Spectral_band_replication AAC SBR] (spectral band replication)
 
 '''Qualification Task:''' See the [https://trac.ffmpeg.org/query?status=!closed&keywords=~aac FFmpeg bug tracker for AAC issues], fixing one of them or rebasing the existing incomplete BSAC decoder for current git head, or fixing one or more existing bugs are possible qualification tasks.
